Just installed a 3.6 v battery that fit the form factor and touched up the coil. It 'll be interesting to see how long it lasts before replacement is needed. When it gets close to 3v the freq varies by a big margin. The coil was zero'd in with the 3.6v and the rest were less than 5% out I suspect this is well within the pass band of the tunings for the functions. I've not had the TV to test with this time so a touch up may be in order anyway. TVCOLLECTOR is going to test it out.
